Economics is about choices. But how can people be persuaded to make healthy choices, or socially responsible or environmentally friendly choices? Behavioural economists have studied how people can be ‘nudged’ into changing their behaviour. One version of nudge theory is ‘fun theory’. This studies how people can be persuaded into doing desirable things by making it fun to do so.
I came across the first video below a couple of days ago. It looks at a highly successful experiment at the Odenplan underground station in Stockholm to persuade people to make the healthy choice of using the stairs rather than the escalator. It made doing so fun. The stairs were turned into a musical keyboard, complete with sound. Each stair plays a piano note corresponding to its piano key each time someone treads on it. As you go up the stairs you play an ascending scale.
After installing the musical staircase, 66% more people than normal chose the stairs over the escalator.
The fun theory initiative is sponsored by Volkswagen. The Fun Theory website is ‘dedicated to the thought that something as simple as fun is the easiest way to change people’s behaviour for the better. Be it for yourself, for the environment, or for something entirely different, the only thing that matters is that it’s change for the better.’
VW held a competition in 2009 to encourage people to invent fun products designed to change people’s behaviour. There were over 700 entries and you can see them listed on the site. The 13 finalists included the musical staircase, traffic lights with quiz questions on the red, a Connect Four beer crate, fun tram tickets (giving entry to an instant-win lottery), a pinball exercise machine, a speed camera lottery where a winner is chosen from those abiding by the speed limit, a jukebox rubbish bin (which plays when people add rubbish), a one-armed vending machine, a fun doormat, car safety belts linked to a car’s entertainment system, car safety belt with a gaming screen which turns on when buckled, a bottle bank arcade system and the world’s deepest bin (or at least one which sounds as if it is). The winner was the speed camera lottery.

- Other than through having fun, how else may people be nudged into changing their behaviour?
- Go through some of the entries to the Fun Theory Award and choose three that you particularly like. Explain why.
- Invent your own fun theory product. You might do this by discussing it groups and perhaps having a group competition.
Australia is a rich country. It is one of the few to have avoided a recession. This has been the result partly of successful macroeconomic policies, but largely of the huge mining boom, with Australia exporting minerals to China and other fast growing Asian economies.
But has this growth brought happiness? Are Australians having to work harder and harder to pay for their high standard of living? Indeed, do higher incomes generally result in greater happiness? The following articles explore this issue, both in an Australian context and more broadly. They look at some recent evidence.
For example, in one study, Canadian, Chinese, Indian, and Japanese university students were asked what they held to be most important for assessing the worth of their lives. The crucial finding was that although higher incomes may be a contributing factor to increased happiness and well-being, especially for poorer people, other factors are more important. These include developing fulfilling personal relationships, whether with partners, family members or friends; gaining knowledge and wisdom; having enjoyable hobbies; having financial security (as opposed to higher incomes); having a worthwhile career; living a moral life; helping other people.
The question then arises whether our economic systems and incentives are geared towards achieving these outcomes. Or are we encouraged to consume more and more and to seek higher and higher incomes to feed our addiction to consumption?
Is there an information problem here? Do many individuals perceive that money will buy them happiness, whereas, in reality, money can’t buy them love?

Questions
- Distinguish between necessary and sufficient conditions. Is higher income a necessary or sufficient condition (or both or neither) for an increase in happiness? Does a person’s circumstances affect the answer to this question?
- Explain what is meant by ‘rational behaviour’ at the margin in the traditional economic sense?
- If a person always behaved rationally, would they be happier than if they did not? Explain.
- Explain how information asymmetry between the two or more parties involved in a transaction may make people worse off, rather than better off, even though they were behaving rationally.
- Explain what is meant by diminishing returns to income.Do richer countries get happier as they get richer?
- How would you set about measuring happiness?
- What do you understand by the term ‘hedonic elevation and decline’? Does this provide an accurate description of you own purchasing behaviour? If so, explain whether or not you would like to change this behaviour.
- When people make economic decisions, these are normally made with bounded rationality. How may this affect the desirability of the outcomes of the decisions?
- In explaining bankers’ behaviour, Christopher Howse (author of the second Telegraph article above) states: ‘It’s the power game that keeps them happy, not the money itself. When I say “keeps them happy” I mean “feeds their addiction”. It is a negative kind of satisfaction. A morning spent without the distraction of making big bucks is a morning left exposed to the empty horror of being a little rational animal on the bare surface of the Earth lost in space.’ Do you agree? Explain why or why not.
- When people are addicted to something, would doing more of it be classed as irrational? Explain.

A recent article on this blog discussed the likelihood that we will soon move to a cashless society. It is therefore interesting to consider the implications that this might have for consumer behaviour. We might expect the form of payment to make no difference to a rational consumer. However, there is considerable evidence to suggest that this is not the case.
One reason why people appear to spend more freely on credit cards is payment decoupling – you get utility from the item purchased before you pay the cost. However, more recent evidence suggests that this is not the only relevant factor. It appears that the degree of transparency of the payment method also has an effect. Psychologists quoted in the above article conclude from their experimental evidence that:
Payment modes differ in the transparency with which individuals can feel the outflow of money. ….with cash being the most transparent payment mode.
This effect also appears to make people spend cash less freely.
The author of the above article spent some time experimenting with trying to make all his purchases using cash. He found that by doing so, he was able to reduce his spending by about 10%. However, this seems likely to become harder to do in the future and, as the article concludes, it is already difficult to purchase some items with cash.

Questions
- What type of products is it already difficult to purchase with cash?
- How did the psychologists test the transparency of payment methods?
- Do you think the consumer behaviour described above is likely to persist in the long-run?
- Might firms be able to take advantage of the consumers behave described above?
- Do you think the transparency of foreign currencies is the main reason why people spend more when they are abroad?
A key economic principle is that rational decision making requires thinking at the margin. This involves a comparison of the additional (or marginal) benefits and costs of an activity.
An example of such rational behaviour would be deciding to drink one more beer or spending one more hour studying only if the additional benefits were greater than the additional costs. The optimum is where marginal benefit equals marginal cost.
And this applies to firms too. A firm maximises its profits by producing the output at which marginal revenue is equal to marginal cost.
However, a recent book by the American business guru Clayton Christensen argues that thinking in this way can be a problem. A recent article in the Guardian describes a story he tells of the time he refused to play for his university basketball team in a national final which took place on a Sunday and therefore conflicted with his religious beliefs. His decision involved sticking to his principles rather than thinking at the margin. For him, whilst the marginal cost of sacrificing these principles just once may well have been small compared to the resulting benefits, the eventual cost would be much higher.
Christensen also suggests that similar arguments can apply to firm decision making. The above article provides an example he uses of decisions made by executives at the Blockbuster video chain. When smaller rivals started offering movies by mail, Blockbuster instead continued to invest in its existing video store business model. This eventually proved disastrous for the company. The explanation given for this is that building on previous investments made more sense than setting up a mail-order arm which would cannibalise their existing business. On the other hand, an alternative explanation may be that executives at Blockbuster were irrationally allowing sunk costs to affect their decision making.

Questions
- Can you think of a situation where you have decided to stick to your principles rather than think at the margin?
- Why does a firm maximise profit by producing the output at which marginal revenue is equal to marginal cost?
- What do you think are the main costs of setting up a mail-order business?
- Are these costs mainly fixed or variable costs?
- Why is it irrational to take sunk costs into account when making a decision?
- Can you think of a situation where you have been influenced by sunk costs?
In 2009, Nudge: Improving Decisions about Health, Wealth, and Happiness was published. This book by Richard Thaler and Cass R. Sunstein examines how people are influenced to make decisions or change behaviour.
According to Thaler and Sunstein, people can be ‘nudged’ to change their behaviour. For example, healthy food can be placed in a prominent position in a supermarket or healthy snacks at the checkout. Often it is the junk foods that are displayed prominently and unhealthy, but tasty, snacks are found by the checkout. If fashion houses ceased to use ultra thin models, it could reduce the incentive for many girls to under-eat. If kids at school are given stars or smiley faces for turning off lights or picking up litter, they might be more inclined to do so.
The UK government has been investigating the use of ‘nudges’ as a way of changing behaviour, and the House of Lords Science and Technology Committee has been considering the question. It has just published its report, Behaviour Change. The summary of the report states that:
The currently influential book Nudge by Richard Thaler and Cass Sunstein advocates a range of non-regulatory interventions that seek to influence behaviour by altering the context or environment in which people choose, and seek to influence behaviour in ways which people often do not notice. This approach differs from more traditional government attempts to change behaviour, which have either used regulatory interventions or relied on overt persuasion.
The current Government have taken a considerable interest in the use of “nudge interventions”. Consequently, one aim of this inquiry was to assess the evidence-base for the effectiveness of “nudges”. However, we also examined evidence for the effectiveness of other types of policy intervention, regulatory and non-regulatory, and asked whether the Government make good use of the full range of available evidence when seeking to change behaviour.
The report finds that nudges
… used in isolation will often not be effective in changing the behaviour of the population. Instead, a whole range of measures – including some regulatory measures – will be needed to change behaviour in a way that will make a real difference to society’s biggest problems.
So is there, nevertheless, a role for nudges in changing behaviour – albeit alongside other measures? Read the report and the articles below to find out!
